Authorisations/Restrictions of 'Post Difference' in MI24?

Hi all!

I couldn't find a related post about this question so sorry if there was one.

I was looking for the possibility/feasability of restricting the 'Post Difference' button in transaction MI24.

I couldn't locate a direct authorisation code linked to that controller so if there is a way I would very much appreciate your input on this.

Scenario presented to me:

- 'Person/Role A' needs to be able to perform the function

- 'Person/Role B' needs to be able to see/access MI24 but should not use the Post Difference function.

My thoughts are that it's a permanent fixture, whereby if a user can use the transaction, they will always be about to post differences.

Thanks and Kind Regards,

Tom
